The RFID market is expected to grow from USD 19 IN 2019 to USD 13 billion by 2024, a compound annual growth rate (CAGR) of 5.6%. One of the largest contributors to this growth is the adoption of RFIDリストバンド for events.
RFID wristbands are comfortable to wear, waterproof, and secure. Their versatility makes them perfect for lots of events, including festivals, concerts, conferences, and sporting events.
But what exactly are RFID wristbands? And how do they work?
RFID wristbands are structured like any other wristband but with an integrated RFID tag. This guide explores RFID wristbands in more depth, discussing how they work and their many benefits.
RFIDとは？
無線自動識別 (RFID) is a wireless communication technology that uses electromagnetic fields to identify and track objects. The technology requires a system comprising three components:
- アン RFID Tag/Chip
- RFIDリーダー
- An Antenna
An RFID chip is the smallest component in the system and contains all of the data that is to be transmitted. This component is critical, and you must always countercheck the memory/storage capacity before buying one. The higher the storage capacity, the more information you will save.
To protect the chip, it is encased in an RFID inlay which is then bonded to the substrate. The inlay generally consists of an antenna for transmitting and receiving data and at least one semiconductor chip that stores and modifies information (memory & logic).
An RFID antenna is used to broadcast the signal that powers the tag and also receives the backscattered signal that contains the data. The antenna can be printed directly onto the substrate, or it can be a separate component that is connected to the tag inlay.
An RFID reader is used to power the tag and to read/write data to and from the tag. Readers come in several form factors, including handheld RFID readers, vehicle-mounted RFID readers, desktop RFID readers, and fixed RFID readers.
The reader broadcasts a signal that powers the tag, and the tag uses the backscattered signal to communicate data to the reader. The reader can be connected to a computer or other network device to transfer and analyze the data.
What are RFID Wristbands?
RFID wristbands are simply wristbands with an RFIDタグ integrated into them. They are primarily used for event management and security purposes.
Just like any other RFID tag, RFID wristbands have an RFID chip and an antenna. The chip stores coded information about the wearer. The information can be a serial number or any other code that can be used to identify the individual.
The outer anatomy of RFID wristbands is highly customizable. Here are various modification elements that define how an RFID wristband looks:
Substrate Material
This is what you can see and touch. The materials used to make wristbands must meet the following conditions:
- Comfortability. Since RFID wristbands are wearable, they must be comfortable to wear for long periods. The material should not cause skin irritation or allergies.
- Durability. RFID wristbands must be durable enough to withstand the rigors of daily use. They should not tear easily and should be able to withstand extreme temperatures.
- ウォータープルーフです。 This property is optional but preferred in many cases. It ensures the RFID wristband can be worn in all weather conditions without damaging the tag.
When selecting the best RFID wristband, you should always consider these factors. They will directly impact the functionality and efficiency of the wristband. Here are the most common types of substrates used in RFID wristbands:
- シリコーン RFID リストバンド. These are the most popular type of RFID wristbands. They are comfortable, durable, and waterproof, making them ideal for swimming pools, spas, and other water-related activities.
- Fabric Woven RFID Wristbands. Fabric RFID wristbands are made from woven materials such as polyester, nylon, and satin. They are a good choice for events that require a more stylish wristband. However, they are not as durable as silicone wristbands and are not waterproof.
- プラスチック RFID リストバンド。 Plastic RFID wristbands are made out of PVC, ABS, and PET. They are durable and waterproof but not as comfortable as silicone wristbands. Plastic RFID wristbands are often used for security applications.
Your choice of material will depend on your specific application. For example, if you need an RFID wristband for sauna and steam bath access control, you will need a silicone RFID wristband.
But if you need an RFID wristband for a one-time event, like a concert, then comfort is more important than durability. In this case, a disposable RFID wristband would be the best choice. These one-time wristbands are usually made out of paper or light plastic.
Personalization / Branding
The outer appearance of RFID wristbands is also highly customizable. RFID wristbands can be printed with logos, texts, and other designs. They can also be color-coded to match the event theme or the brand identity.
This high-level customization ensures that RFID wristbands perfectly blend in with the event or brand. It also allows event organizers and brands to use RFID wristbands as a marketing tool.
How RFID Wristbands Work
RFID wristbands have a simple working rationale. They use Radio-Frequency Identification (RFID) technology to communicate data.
RFID is a contactless identification technology. It uses electromagnetic fields to automatically identify and track tags attached to objects.
RFID wristbands work in the following way:
- An RFID reader sends an electromagnetic field/ radio waves.
- The RFID tag attached to the wristband absorbs the energy from the field
- The tag uses the energy to power up and reflects the stored information
- The RFID reader picks up the reflected signal and decodes the data
- The decoded data is then transferred to a computer for further processing
The data stored on RFID tags can be anything from simple identification numbers to complex information about the wearer. This data can be read and processed automatically. It can also be used to trigger specific actions, like opening a door or starting a machine.
RFIDリストバンドは主に passive tags. This means that they rely on the reader to power up and communicate data.
Their read distance depends on the type of tag, reader, and environment. In most cases, the read distance is between 0.5 inches (1.3 cm) and 10 feet (3 m). This is enough for most events or other applications.
However, some RFID wristbands come with an integrated battery. This allows them to be used as active tags. Active tags have a much longer & better read range of up to 100 feet (30 m).
Active RFID wristbands are often used for security applications where long read distance is important. For example, an organization that uses RFID wristbands for employee access control would likely use active RFID tags.
Types of RFID Wristbands Based on Frequency Used
RFID wristbands are classified based on the frequency used, including low-frequency (LF), high-frequency (HF), and ultra-high-frequency (UHF) RFID wristbands.
- LF RFID Wristbands
LF RFID wristbands operate at a frequency of 125-134.2 kHz. They have a shorter read range than HF and UHF wristbands. They are common in events that need short-range communication, like access control for saunas and spas.
LF wristbands are less prone to interference from water and metal objects. This makes them more reliable in wet environments.
- HF RFID Wristbands
HF RFID wristbands operate at a frequency of 13.56 MHz. They have a read range of up to 4 inches (10 cm). HF wristbands (also called NFC wristbands) are common in events that need contactless payment, like festivals and concerts.
They use NFC protocols for data transfer. The data is stored in NDEF format, making them compatible with most NFC-enabled devices.
These wearable payment wristbands offer several advantages over traditional payment methods, like cash and credit cards. They are more secure and allow for contactless payments. This reduces the risk of theft and fraud.
They are also regulated by ISO-14443A/B standards. This makes them compatible with most HF RFID readers.
- UHF RFID Wristbands
UHF RFID wristbands operate at a frequency of 860-960 MHz. They have a long read range of up to 10 feet (3 m). UHF RFID tags are common in events that need long-range communication, like festivals and concerts.
These wristbands are the least common type of RFID wristbands. Their long read range is primarily not required in many of the applications where RFID is used.
UHF wristbands are also more susceptible to interference from water and metal objects. This makes them less reliable in wet environments.
